' WIRE-SCRAPING TOOL.

Application filed December 2, 1918.

To aZZ whom it may com-em Be it known that I, ALEXANDER LICHTEN- STEIN,a citizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Vire- Scraping Tools, of which the following is aspecification.

This invention relates to wire scraping tools designed for removingcovering therefrom.

The object of the invention is to provide a device of this class havingmeans for rigidly securing it to a support so that the wire may beeasily scraped.

Another object is to provide a device of this character having wirereceiving notches of varying widths for use in connection with differentgage wires.

Vith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings:

Figure 1 represents a' front view of a wire scraper constructed inaccordance with this invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is a front view showing a slightly different form of theinvention; and

Fig. 4 is a transverse section taken on the line l--4L of Fig. 3.

In the embodiment illustrated in Figs. 1 and 2, the tool constitutingthis invention comprises a plate 1 tapering toward its lower end with alaterally extending arm 2 projecting at right angles from said end andwhich carries a vertically disposed clamping screw 3 having the usualactuating head l. Extending laterally from plate 1 at the enlarged orhead portion thereof is a shelf-like member 5 which is designed to reston the top of the support to which the device is to be attached and thescrew 3 to extend below said support, so that the scraper may besecurely and rigidly clamped to the support, which would ordinarily be ashelf or table.

The head of plate 1 is provided with a plurality of longitudinallyalined scraping Specification of Letters Patent.

fingers 6 spaced apart varying distances to form wire-receiving sockets7 so that wires ofdifferent sizes may be scraped. These fingers 6 havetheir side edges beveled to form cutting blades 8 so that when a wire ispassed into the sockets 7 and drawn through them, the covering carriedthereby will be scraped off by the beveled edges of the cutting fingersor blades 6. At the end of the series of blades is shown a V-shapednotch 7' which is designed for use in connection with large-sized wires.

In the form shown in Figs. 3 and 4., a plate 9 substantially rectangularin form is shown having a plurality of screw-receiving apertures 10, forconnection to a suitable support. A shelf-like member 11 projectslaterally at right angles from the inner face of this plate 9 at a pointabove the apertures 10 and is designed to rest on a table or shelf andis preferably provided with apertures 12 to permit its being fixed tosaid shelf by screws or other suitable fastenings.

The upper edge of the plate 9 is provided similarly to the head or plate1 with a plurality of longitudinally alined cutting blades or fingers 6which are exactly like those in the form shown in Figs. 1 and 2 and aresimilarly spaced and beveled for the same purpose.

The notches or sockets 7 as above described have their edges beveled toprovide cutting knives, the bevel preferably extending at an angle ofabout forty-five degrees, as shown in Fig. 4, so as to cause it to cutinto the covering and scrape the same from the wire.

By fixing this improved device to a support and holding it stationarythereon, the

.wire to be scraped may be inserted in any one of the notches or socketsT and the covering removed with facility, and if desired a plurality ofwires may be scraped simultaneously. The wires are inserted in thenotches from the back of the plate 1 and pulled forwardly so that thecutting edges will be most effective. T

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains; and while I have described theprinciple of operation of the invention together with the device which Inow consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claimas new and desireto secure by Letters Patent, is:

1. A wire scraping tool comprising a plate having its edge divided intoa plurality of variously spaced teeth each tooth of the same Width, andone relatively broad end tooth provided with a V-shaped notch in itsextremity.

2. A wire scraping tool of an integral structure comprising a bladeportion divided into a plurality of variously spaced teeth, anintegrally depending portion neath the support, said extension having avertical threaded aperture, and a screw inserted in said aperture toengage the under side of the support.

In testimony whereof I aflix my signature in presence of two witnesses.

ALEXANDER LICHTENSTEIN.
